=head1 NAME

t::lib::Mocks::Zebra - Trying to mock zebra index

IMPORTANT NOTE: This module is not working as you may think it could work.

It will effectively create a new koha-conf.xml file in a temporary directory with zebra config files correctly.
So it will not affect the koha-conf used by plack (and so the UI).

If you pass koha_conf to the constructor the usual zebra db will be used, otherwise a new koha-conf.xml file will be generated
and the usual zebra db will not be affected. However you must pass $ENV{KOHA_CONF} if you want to test the UI.
